challenge is my game

[ronsabgand]

Write a program that, when run, will print out its source code. This source code, in turn, should compile and print out itself. (Fun fact: a program that prints itself is called a quine.)

#include <stdio.h>
char *program = "#include <stdio.h>%cchar *program = %c%s%c;%cint main()%c{%c
printf(program, 10, 34, program, 34, 10, 10, 10, 10, 10, 10);%c return 0;%c}%c";
int main()
{
printf(program, 10, 34, program, 34, 10, 10, 10, 10, 10, 10);
return 0;
}

this is an exmple from my teacher homoepage.
i want to uderstand what the program is doing. can someone explain what the (*) does and why the printf has the same thing again.
